This invention relates to an improved automotive appliance which may be conveniently entitled a glass extracting or removing device, and it has more particular reference to an especially designed structure intended to facilitate the displacement of broken glass from a metal retaining channel.

The invention has more particular reference to a device of this class which is prim marily designed for use in automotive garages and analogous places where it becomes necessary to force out broken glass from a retaining channel constituting a part of a sliding window used in present-day closed types of automobiles.

In the drawings:

Figure 1 is a side elevational View of a device constructed in accordance with the present invention showing the method of usage.

Figure 2 is a longitudinal sectional View, the section being on the line 22 of Figure 4.

Figure 3 is a top plan view.

Figure 4 is an end elevation observing the structure in Figure 1 from left to right.

Figure 5 is a cross section on the line 5-5 of Figure 3.

. Figure 6 is a similar cross section on the line 66 of Figure 2.

Figure 7 is a fragmentary detail sectional and elevational view of the headed end of the mechanically operated ejector.

The invention is characterized by a clamping device somewhat in the nature of a vise and it comprises an elongated base or body member 8 having apertured attaching ears 9 at its opposite ends designed to be fastened to a bench of appropriate support. This device 8 is formed with a central longitudinal channel 10 which opens through the right hand end and which is closed at the left hand end as indicated at 11.

The last-named end 11 is provided with an upstanding U-shaped abutment 12 which functions as a keeper and which is designed to receive one end of the channel 13 holding the glass 14. These features 13 and 14 may be portions of a sliding window 15 such as is used in present-day automobiles.

Adjacent the open end of the channel are elevated spaced parallel side walls having their upper end portions terminating in bearings '16 for transverse rotary shaft 17 On one end of the shaft 17 is a handorank and on the intermediate portion is a pinion 19 which has its teeth in constant mesh with the teeth of the rackbar 20 of the ejector 21. This ejector includes a wedge-shaped head 22 which as shown in Figure 7 has its terminal end fashioned with a shoe 23 to ride in the channel 13. The inner end of the head is formed with a retaining shank 24; fitting into a socket inthe rackbar, and a pocket forming portion 25 which receives the socketed end of the rackbar.

The numerals 26 and 27 in Figure 2 designate longitudinally spaced parallel transverse guide rollers which constitute rests for the slidable rackbar.

The gist of the invention, it will be understood is in the provision of a clamping device somewhat in the nature of a vice having channelled base with attaching means and also formed at one end with a keeper to receive the glass containing channel of the window 15. At the opposite end is guide means for the longitudinally reciprocatory rack bar and associated with the guide means is the pinion carrying crank rotated shaft for forcing the wedge-shaped ejecting head into the channel to lift the glass therefrom, to crush the glass and to force the glass out, thus cleaning the channel.

It is thought that the description taken in connection with the drawings will enable a clear understanding of the invention to be had. Therefore a more lengthy description is thought unnecessary. While the preferred embodiment of the invention has been shown and described, it is to be understood that minor changes coming within the field of invention claimed may be resorted to if desired.

I claim:

1. In a glass ejecting device of the class described, a channel-shaped base adapted to be attached to a relatively stationary support, a keeper at one end of the base, and guide means at the opposite end of the base, and a reciprocatory ejecting device associted with said guide means, said device being in the form of a rack bar having a Wedgeshaped head on its inner end adapted to ride along and in the channel holding the glass.

2. In a structure of the class described, a channeled base having attaching means, and an upstanding U-shaped keeper at one end, upstanding spaced parallel guide means at the opposite end including longitudinally spaced rollers, a transverse shaft rotatably mounted in bearings above said rollers, a pinion carried by said shaft, an operating crank for the shaft, a rack bar slidable between said guide means and resting on said rollers, said pinion having its teeth engaging the teeth of said rackbar, and a Wedge-shaped head on said rack bar designed for movement in the glass containing channel for forcibly removing the g'lass therefrom.

In testimony whereof I aflix my signature.

JOHN K. MERNECK.
